other crops, non-tillage methods to alleviate compaction CROP COVER ROOT CHANNELS MAY problems have not been extensively researched. DeepALLEVIATE SOIL COMPACTION rooted cover crops are one possible solution to compaction problems, especially in no-till farming systems (UnEFFECTS ON SOYBEAN CROP ger and Kaspar, 1994). The deep growing tap roots of the perennial alfalfa (Medicago sativa L.), can...

crop productivity, water use efficiency (wue), and microbial biomass c and n in rainfed dry area are influenced by tillage, rotation, and crop residue management. field experiments were conducted during 2005-08 to study the effect of tillage, crop rotation, and crop residue retention on oat fodder yield, water use efficiency, and microbial biomass c (mbc) and n (mbn) under semi-arid conditions ...

A recurrent issue for data integration is the lack of a common and structured vocabulary used by different parties to describe their data sets. The Crop Ontology (www.cropontology.org) project aims to provide a central place where the crop community can gather to generate such standardized vocabularies and structure them into ontologies. Having standardized ontologies opens the world of the Sem...
